The Celtics, the leaders of the dreadful Atlantic Division, fell to 10-14 with their second straight loss.

Celtics guard Jordan Crawford, the reigning Eastern Conference player of the week, had 20 points, nine assists and five rebounds and forward Brandon Bass 17 points and 12 boards in the loss.

Rivers was greeted with a standing ovation when he walked out of the locker room before the game, then got another hand during the introductions. A video tribute was played between the first and second quarters and Rivers turned and watched, then acknowledging another ovation.

The Clippers fell behind by nine in the first half and were down by six at the break.

Los Angeles took a four-point lead 4:16 into the second half, then fell behind by four, but took the lead by the end of the third quarter. An old-fashioned 3-point play by Jamal Crawford gave Los Angeles a five-point lead a minute into the fourth quarter.

Late in the first half, the Celtics intentionally fouled Los Angeles big man DeAndre Jordan, who came in leading the league in field goal percentage and was last — by a lot — in foul shooting percentage. He went 1-for-4 from the line in the first half and missed two in the third quarter.Notes: Before the game, n Rivers met the media and greeted old friends and former players in the hallway. “I’m an emotional guy,” Rivers said. “I just hope I can coach the team tonight and get through it.” ... “The Rivers Reunion Tour” hits Brooklyn tonight, when the Clippers visit the Nets and former Celtics forwards Kevin Garnett and Paul Pierce. ...
